Pentax Zoom 70-x won't take pictures, Error code E7

Does that camera have a battery to advance the film and operate the unit? U might just want to check that out and replace the battery. If nothing happens with new battery, then the camera is fubar.

This question has been answered repeatedly. Pentax error codes are mostly for camera repair technician diagnosis and most of the time mean the camera is broken and needs professional servicing. Some Pentax Error Codes:
E: "E" often indicates a film jam. This code can appear when the film is inserted incorrectly, when the batteries are changed in the middle of a roll of film, if you are using defective film, etc. If "E" appears in your camera's information display, try to rewind your film manually (see your user's guide for instructions on how to activate your mid-roll rewind function), and try a different roll. If this problem keeps occurring, you might need to send the camera to us for repair.
E3, E7, E37: These codes often signal a problem with your shutter mechanism.
E9, E93-E97: These codes may indicate a problem with your zoom lens.
H0-H9: These H codes can also identify a problem with your camera's shutter.
U1-U9: These U codes may also indicate a problem with your camera's zoom lens.

These codes are standard for both Digital and film cameras.

If you press the film release button like you are going to rewind exposed film you may be able to activate the film advance lever to cock the camera so you can take another picture, and the film should stay on the first exposure allowing you to re - expose it. I would underexpose each image 1 F stop because.you are exposing the same film twice. Double exposures are always an iffy proposition and anything can happen. After the second exposure cocking the film advance should allow the film to advance once again. You might test this on the final pictures on a roll in case the camera won't start advancing the film after you try it. This way you won't blow a whole roll worth of pictures testing it.

Even though it was cushioned somewhat the camera took enough damage to jam something. The flashing symbols are a generic error code it could mean the shutter, zoom, film transport, flash, or some combination of these system are not working (sorry but without tearing the camera apart I can't narrow the problem any further)

Take it for a service

gebje,

error codes on pentax camera's are in the repair manual to help the technician find the problem faster. e9 is shutter failure and will need to be repaired.

Listing of Pentax codes E3, E7, E37: These codes often signal a problem with your shutter mechanism. E9, E93-E97: These codes may indicate a problem with your zoom lens. H0-H9: These H codes can also identify a problem with your camera's shutter. U1-U9: These U codes may also indicate a problem with your camera's zoom lens.

i think it means the film hasn't loaded properly. I had this and opened up the back and the film hadn't wound so it wasn't exposed. Anyway i just wound the film around a bit and shut the back and it turned on like normal. hope this helps. 

This is a zoom error code - the flexible circuit going to the shutter in the barrel is probably worn out. It'll have to go to a repair shop.

The IQ Zoom cameras are designed to display error codes (E0, E2, E9, E10, E1A, E37, E90, HL, H4, H5, etc.) when something goes wrong internally with one of the mechanisms or electronic components. These diagnostic displays help to determine where the problem is. When you see an error code, ask a qualified PENTAX repair technician to examine the camera.
